We prepared glass-ceramics reinforced by ß-wollastonite using waste fluorescent glass to resolve the environmental problem. Fluorescent glass and calcium carbonate were used as starting materials. The chemical durability of specimens heat-treated at 800 °C, 900 °C, and 1000 °C was analyzed by both measuring weight change and observing surface morphology. Specimen composition was determined with energy dispersive X-ray spectroscopy. As the heat treatment temperature was increased from 800 °C to 1000 °C, the chemical durability decreased, especially in the glass-matrix area. A compressive strength of about 250-350 MPa was sufficiently large for practical use.
